Assuming that your newsreader inserted line breaks where there are none
in the code, the above statement gives the following on my windows:

    % exec test_argc rmtshare \\\\jack\\$newValue$=c:\\test\\profiles\\$newValue$ /GRANT everyone:full
    4
    1/4 {rmtshare}
    2/4 {\\jack\tdurden$=c:\test\profiles\tdurden$}
    3/4 {/GRANT}
    4/4 {everyone:full}

I'm calling test_argc which is a program to simply print the individual
arguments passed to it (see attached code).  Seems ok to me.  So the
next step at your side would either also use such a program to see what
is actually arriving at the exec'd side, or use TWAPI as someone else
suggested (if this is an option).

R'

/* test_argc.c -- print number of arguments excluding program name to stdout */
#include <stdio.h>
#include <string.h>

int
main(int argc, char *argv[]) {
  printf("%d\n", argc-1);
  for (int i =1; i < argc; i++) {
    printf("%d/%d {%s}\n", i, argc-1, argv[i]);
  }
  printf("\n");
  return argc-1;}

/* End of file */

Note that this debugging application gives rise to an additional layer
of command line parsing by the C library and it's not necessarily the
case that the ACL command line applications even use an argv array.
The windows CreateProcess API call takes the whole commandline as a
single string (and this should be reflected in [exec] behaviour on
windows IMO) To know exactly what was passed to createprocess, use
WinMain or add some debugging code to the call in the [exec]
implementation.

Regards,
Mark

Note that in this case this doesn't differ. The command line sent to
CreateProcess is:

rmtshare \\jack\tdurden$=c:\test\profiles\tdurden$ /GRANT
everyone:full

As returned by:

#include <windows.h>

int WinMain (
HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow ) {

MessageBox (NULL, lpCmdLine,"Arguments",MB_OK);
return 0;
}

.
